Diagnosis

Your muscle activity may be measured. This can be done with an electromyogram (EMG).

Images may be taken of your bodily structures. This can be done with an
MRI
scan.

Treatment

The disease is progressive and starts slowly. If left untreated, the muscles gradually become weaker. The pain in the muscles also increases. While there is no cure, treatment can improve your muscle strength and function. Talk with your doctor about the best plan for you. Options include:

Medication

Medications to treat polymyositis may include:

Corticosteroids to reduce inflammation

Other immunosuppressants

IV
immunoglobulin therapy
is another treatment option. It involves using an IV needle to inject extra immunoglobins (special proteins) into the body. This process may help the immune system function better and reduce inflammation.

Physical Therapy

Your doctor may recommend that you work with a physical therapist to prevent permanent muscle damage. Exercise may include:

A regular stretching routine for weakened arms and legs

Light strengthening as the pain lessens and function returns

Dietary Changes

Polymyositis can lead to problems with chewing and swallowing. By working with a registered dietitian, you can learn ways to adjust to these changes and get the nutrition that you need.

Speech Therapy

Polymyositis may also cause speech problems. A speech therapist can assess your condition and create a program for you.
